Menstruation is half a month late and hasn't arrived yet. What could be the reason?

Patient's question:

No

Doctor's answer:

Hello, first make sure to check if you are pregnant. Also, pay attention to fatigue, poor rest, or mental stress and anxiety, as well as environmental changes and gynecological inflammation, which can all lead to delayed menstruation. It is recommended that you go to the hospital to check if it is caused by gynecological inflammation or endocrine disorders. It is suggested that you identify the cause and receive targeted treatment.
